Abstract

A heat flow of 1.2 ±.1 μcal cm−2s−1 has been measured in a mine at Eldorado, Saskatchewan. The uncertainties in the correction to this value for climatic changes caused by the most recent glaciation are a minimum at the depth at which this measurement was made. A terrestrial heat flow value, representative of the area, was obtained by using a two-dimensional conductivity model of the mine; this value is 1.3 ±.1 μcal cm−2s−1.
